Abstract: A radome includes a laminated structure (42) in the form of a stack of composite layers (44, 46, 48, 50), each composite layer (44, 46, 48, 50) including a fibrous reinforcement mixed with an organic matrix. The composite layers includes at least one high-permittivity layer (44, 50), including a structural layer (44), and a plurality of low-permittivity layers (46, 48), including two covering layers (46, 48) sandwiching the structural layer (44) between them, each of the covering layers (46, 48) having a lower thickness to the thickness of the structural layer (44). In each low-permittivity layer (46, 48), the fibrous reinforcement includes a majority of polyolefin fibers.
